7 Specification of Lettersl'atent. Patented May 23, 1911.

Application filed March 30, 1910. iserial No. 552,304.

To all whom it may concern:

Be it known that I, GUSTAF AKERLUND, a

: subject of the King of Sweden, residing at Atlanta, county of Fulton,and State of Georgia, have invented certain new and useful Improvementsin Gas-Producer Systems, of which the following is a specification.

This invention relates to gas producer systems- V r The presentinvention has for its object the provision of a complete gas producersystem comprising a generator, as cooler, scrubber, purifier, exhausterand tank, all of novel constructlonand arranged and-adapt- .ed forconjoint use to produce, cool, clean,

purify and store gas for use at anypoint- The generator, which is of thewater-seal,

"conical ash pier type,-embodies;a novel ar- 'rangement of its shell inthe water-pit so that all of themetal parts are protected by the seal,an ash-pier arranged in the pit in such fashion that building up of theclinkers at the center is obviated and the breaking up of the clinkersand removal of the ashes through the water-pit is facilitated, a novelarrangement of the vaporizer and supply of water thereto, rendering theWater level always constant, a new arrangement of vapor distributor withcontrolling valve so that the vapor supply can be regulated, and

a new air intake,

The gas cooler is-constructed so that it may be cut oil from theremaining units of the system and embodies independent cornpartmentswith water sprays, said compartments each having its own direct drain,water-sealed so thatthe impurities washed out of the gas readily drainoff without necessitating operation of any valves, and, a water-sealedvalve connecting the compartments which has filling and draining connections and means for regulation of the water level.

' The scrubber and purifier combines separate compartments or'ehamber'sand a gas duct or. trunk so arranged that the heat u'hichuii'i radiatedfrom. the purifier is absorl ed" by the wat r spraysin these-rubber,

and thus the purifier is kept comparatively ez-ol and eil'ecis a furthercooling of the gas after it leaves the scrubber and enters the purifier,The s rubber has a grate constructed and arranged in a novel mannerpermitting easy renewal of the coke, and the is the conical ash-pier 3.

purifier has cleaning and filling doors disposed adjacent the trays in anew manner so that one canlbe used for cleaning and the other forfilling any given compartment.

The system contemplates the use of an exhauster, and various adjuncts,whereby the draft in the generator can be reversed from downward toupward without stopping or reversing the exhauster.

The accompanying drawing is a longitudinal sect-ion through the completesystem.

The generat0r.-The entire system or plant is preferably supported 011 asuitable concrete or other foundation 1 and at the point where thegenerator is located this is circular form, and rising centrally thereofThe" generator is supported on pillars 4, the lower metallic part 5 ofthe generator, which is in the form of a shell, being immersed in thewater in the pit 2 so that it is always protected against the heat andthe seal-is suificiently deep to prevent the exhaust or suction of thesystem from breaking the seal at this point.

The generator 6 may be of any preferred form with filling opening,twyers, and other provided with a water-pit 2 preferably of adjuncts,but the lower part thereof is provided witha tapering shell 7 whichissur rounded by a circular shell 8, the two being designed to form anannular channel containing water. Air isintroduced into space abovesluri'aceot the Water and preheated during itsco'u'rse through one ormore induction pipes 10, open to atmosphere atone end; the preheated airthus introduced mixes with vapor rising from the water and arisesthrough one or more pipes 10 so that the air and vapor may mix and befed to the generator 6 by the mixture intake 12; the mixture issuperheated during passage through pipe 10. To control and regulate theamount of mixture, I provide an adjustable valve 13. There is alsoprovided a stack 14 which communicates with a duct 15, whereby air maybe let into the generator,

and this in turn, maybe controlled by a damper 16 in the stack 14: sothat any de- 'duced by the generator passes into the cooler ber issupported on a grate 36 which is always maintained at the same height.The pipe coupling has a removable plug by which the draining of thevaporizer can be readily effected, and by any desiredadjustment of theover-flow pipe, the water level in the vaporizer can be changed asdesired.

The cooler is preferably composed of two upright tubular compartments 19and 20, each having a series of sprays 21 arranged. vertically insuccession, the two compartments being connected by a cooler watertrapvalve 22 which may be drained by a valved pipe 23 leading from thebottom thereof and suitably filled by a' valve pipe 24 leading to thetop thereof. The watertrap cooler valve 22 is normally empty and openfor the passage of the gas, but when the producer is dormant, this valveis filled with water to cut the generator of from the rest of thesystem. The gas provia a trunk 2.5,whence it rises, is cooled by thesprinklers 21, then dives through the watertrap cooler valve 22 andfinally passes into the compartment 20 for its next sprinkling.

The compartment 19 has: a direct drain 26, by which the impuritieswashed out of the gas are gravitally carried off without requiring theoperation of any valve, and this drain is sealed by the water in the pit2, or otherwise. The compartment 20 has a similar water-sealed drain 27which also serves as a drain for the scrubber to which the coolerconnects at 28.

The scrubber and purifier are contained in the same shell 29, thescrubber compartment being shown at 30 and the purifier at 31, the twobeing separated by a partition 32, on which is formed a diving duct ortrunk 33, which opens into the upper part of the scrubber at 34 and intothe lower part of the purifier at 35. The coke in the scrubhinged at 37and is adapted to swing'downwardly to deliver the coke to the inspectiondoors 38, thus rendering easy the renewal of the coke. In the upper partof the scrubber is a sprinkler 39 to keep the coke moist, the sprinklerbeing controlled by a suitable valved pipe 40. The impurities washed outof the gas by the scrubber drain down through the pipe 27. The gas whichenters the scrubber through the opening 28, passes upwardly through thecoke, is cleansed and cooled and thendives down the trunk or duct 33 andpasses into the lower part of the purifier at 35, whence it risesthrough the various beds or strata 41, supported by screens 42 andfinally passes into the pipe 43. On a level with each of the beds orstrata 41 is a cleaning door 44, and just above the bed is a fillingdoor 45, thus affordinga convenient arrangement for cleaning and fillingeach compartment of the purifier. The heat radiated through thepartition 32 is absorbed by the water spray and the coke in thescrubber, thus rendering it possible to still further cool the gas afterit enters the purifier.

The exhausts?" and 0c-.-.ss02"z'es.-The exhauster 4G- is connected tothe pipe 43 and by suction draws the gas through the system, deliveringit" into the watersealed valve 47 whence it issues into the expansiontank 48, from which the gas is taken to the pipe line.

Reversal of draft.-To provide for a reversal of the draft v ithoutnecessitating stoppage or reversal of the exhauster, there is providedan air inlet valve 49, which is only opened when the draft is to bereversed, beingat other times closed, and an up-draft air pipe 50 havingsuitable controlling valve 51 which is only opened when the draft is tobe reversed, said air pipe leading into the compartment 19 of the coolerat 52.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a gas producer, the. combination of a generator, a cooler, ascrubber and purifier, said cooler scrubber and purifier being arrangedto successively treat the gas produced by the generator, anexhausterhaving a pipe connection with the purifier, and a separatevalved up-draft pipe connection leading from the exhauster to thegenerator, whereby the draftmay be reversed without stopping orreversing the exhauster.

2. In a gas producer, the combination of a generator, a cooler, ascrubber and purifier, said cooler scrubber and purifier being arrangedto successively treat the gas produced by the generator, an exhausterhaving a pipe connection with the purifier, a separate valved up-draftpipe connection leading from the exhauster to the generator, whereby theIn testimony whereof. I hereunto affix my signature in presence of twowitnesses.
